Query regarding AlertDialog

I have to make a dialog with 2 editfields and a process which will be handled in AsyncTask on a button click. I found that I can add editfields in alertdialog and work out. My queries are :
1) In the AsyncTask process, I will also have to show a ProgressDialog. Can I show a ProgressDialog on top of AlertDialog ?
2) To make coding simple and easy, I wuold prefer if I can extend AlertDialog. Is it possible to extend AlertDialog or should I extend AlertDialog.Builder ? I am confused with this state.
3) In whichever button presses, eventually the dialog will be closed, but need to run AsyncTask on positive button. Is it fine to work like this with an AlertDialog !
4) Will AlertDialog also handle the orientation part on its own like Landscape or portrait as it is suppossed to do.

Orientation do affect Alert Dialog.
You can handle AsyncTask too. Just call some method on positive button of AlertDialog.And you can display progressDialog from that method.runOnUiThread I think help you out.
You can make your own customize Alert Dialog too.

Thanks Hardik.

What do you mean by - "Orientation do affect Alert Dialog."
Do you mean that it handles itself and we don't need to code or handle ? Whereas in custom dialog we need to handle it ourselves !!

Well, On positive button clickI will call AsyncTask object. In that only in onPre I will open ProgressDialog and in onPost close the ProgressDialog. I guess this will be running on UI thread only via AsyncTask !!!
